PCI using the virtual 3‐Fr system was attempted as our initial strategy, unless a 6‐Fr or larger GC was considered to be suitable [lesions with heavy calcification, large (>2 mm) side branches, or chronic total occlusion].</p> </sec> <sec id="ccd25357-sec-0004" sec-type="section"> <title>Results</title> <p>Five hundred sixty‐six patients underwent elective PCI during the study period, and 132 patients who met the criteria underwent PCI using the virtual 3‐Fr system. Procedures using the virtual 3‐Fr system were successful in 126 patients (95%); 111 (84%) were performed using the transradial approach, 110 (83%) were ad hoc procedures, and 45 (31%) were complex coronary lesions (type B2 or C). Six patients required conversion to a conventional 5‐ or 6‐Fr sheath and catheter system. No intraoperative complications occurred, and radial artery patency was achieved in all patients who underwent transradial procedures.</p> </sec> <sec id="ccd25357-sec-0005" sec-type="section"> <title>Conclusions</title> <p>PCI using the virtual 3‐Fr system is a feasible and viable alternative to conventional procedures that use a sheath and GC in appropriately selected patients. This small‐caliber system may minimize endovascular trauma, particularly during transradial coronary procedures. © 2014 Wiley Periodicals, Inc.</p> </sec> </abstract>
